TCA ROOFTOP UNITS Service Literature TCA 180 210 240 300 (10 08) The TCA180S, 180H, 210S, 210H, 240S, 240H and 300S are available in one cabinet size with cooling capacities from 180,000 to 286,000 Btuh (45.7 to 83.8 kw). TCA 15 through 25 ton Optional electric heat is field installed in TCA units. Electric heat operates in single or multiple stages depending on the kw input size. 15kW to 60 kw heat sections are available for the TCA180S, 180H and 15 kw to 90 kw heat sections are available for the TCA210S, 240S, 210H, 240H and 300S. TCA180, 210S and 240S units utilize three compressors and TCA210H, 240H and 300S units utilize four. All units are designed to accept any of several different energy management thermostat control systems with minimum field wiring. Information contained in this manual is intended for use by qualified service technicians only. All specifications are subject to change. Procedures outlined in this manual are presented as a recommendation only and do not supersede or replace local or state codes. If the unit must be lifted for service, rig unit by attaching four cables to the holes located in the unit base rail (two holes at each corner). Refer to the installation instructions for the proper rigging technique. WARNING Improper installation, adjustment, alteration, service or maintenance can cause property damage, personal injury or loss of life. Installation and service must be performed by a licensed professional installer or service agency. WARNING Electric shock hazard. Can cause injury or death. Before attempting to perform any service or maintenance, turn the electrical power to unit OFF at disconnect switch(es). Unit may have multiple power supplies. ELECTROSTATIC DISCHARGE (ESD) Precautions and Procedures CAUTION Electrostatic discharge can affect electronic components. Take precautions during unit installation and service to protect the unit s electronic controls. Precautions will help to avoid control exposure to electrostatic discharge by putting the unit, the control and the technician at the same electrostatic potential. Neutralize electrostatic charge by touching hand and all tools on an unpainted unit surface before performing any service procedure. Table of Contents Specifations....................

I UNIT COMPONENTS TCA unit components are shown in figure 1. All units come standard with removeable unit panels. All L1, L2, and L3 wiring is color coded; L1 is red, L2 is yellow, and L3 is blue. A Control Box Components TCA control box components are shown in figure 2. The control box is located in the compressor compartment. 1 Disconnect Switch S48 (field installed) All units may be equipped with an optional disconnect switch S48, or circuit breaker, CB10. S48 and CB10 can be a toggle switch or a twist style switch. Both types can be used by the service technician to disconnect power to the unit. CB10 when use, will be in the same location as S48 on the wiring diagram. 2 Terminal Strip TB2 All units are shipped with factory installed TB2. Units without S48 or CB10 will have supply power connected to TB2. 3 Control Transformer T1 (all units) All use a single line voltage to 24VAC transformer mounted in the control box. Transformer supplies power to control circuits in the unit. The transformer is rated at 70VA and is protected by a 3.5 amp circuit breaker (CB8) which is located on the transformer itself. The 208/230 (Y) voltage 208/230V TRANSFORMER transformers have two BLUE YELLOW SECONDARY primary voltage taps, but only one may be 208 VOLTS used depending on RED supply voltage. See 230 VOLTS figure 3. 460 (G) and PRIMARY ORANGE BLACK 575 (J) voltage transformers use a single FIGURE 3 primary voltage tap. 4 Contactor Transformer T18 T18 is a single line voltage to 24VAC transformer used in 4 compressor units only. Transformer T18 is protected by a 3.5 amp circuit breaker (CB18) located on the transformer itself. T18 is identical to transformer T1. The transformer supplies 24VAC power to the contactors. 5 Terminal Strip TB1 All indoor thermostat connections will be to TB1 located on MCC board A45. For thermostats with occupied and unoccupied" modes, a factory installed jumper across terminals A1 and A2 should be removed. Unit wiring is designed for a three stage thermostat. For two stage applications jumper between Y2 and Y3 on TB1. 6 Terminal Strip TB14 Terminal strip TB14 located on the MCC board A45 distributes 24V power from transformer T1 to the control box components. Units not equipped with smoke detectors A17 or A64, will have a factory installed jumper across terminals 24VAC and R. 7 Outdoor Fan Capacitors C1, C2, C18 & C19 Fan capacitors C1, C2, C18, C19 are 10 MFD / 370V capacitors used to assist in the start up of condenser fans B4, B5, B21, B22 respectively. 8 Outdoor Fan Relay K10 & K68 Outdoor fan relays K10 and K68 used in all units, are DPDT relays with a 24VAC coil. In all TCA units K10 energizes condenser fans B4 and B5 and K68 energizes condenser fans B21 and B22. 9 Fuses F10 and F6 Two line voltage fuses F10 provide overcurrent protection to all condenser fans in all Y voltage TCA units and rated at 30A. Fuses F6 provide overcurrent protection for optional field installed power exhaust fans and rated at 15A. 10 Compressor Contactor K1, K2 & K14 (all units) K146 (TCA 210H, 240H, 300S units only) All compressor contactors are three-pole-double-break contactors with 24VAC coils. In all TCA180, 210S and 240S units, K1, K2 and K14 energize compressors B1, B2 and B13 in response to thermostat demand. In the TCA210H, 240H and 300S units, K1, K2, K14 and K146 energize compressors B1, B2, B13 and B20 in response to thermostat demand. 11 Blower Contactor K3 Blower contactor K3, used in all units, is a three-pole-doublebreak contactor with a 24VAC coil used to energize the indoor blower motor B3 in response to blower demand. K3 is energized by relay KD on the A45 MCC board. Page 20
